IMPROVEMENT IN HORSE-POWER WINDLASSEFS.

Specification forming part of Letters Patent No. 36,14 '2, dated August 12, 1862.

To all whom it may concern/.-

Be it known that we, L. DEDERIOK and P. K. DEDERIOK, both of Albany, in the county of Albany and State of New York, have invented a new and Improved Horse-Power Windlass; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this speciiication, in which-A Figure l is a vertical central section of our invention, taken in the line m x, Fig. l. Fig. 2 is a plan or top view of the same.

Similar letters of reference indicate corresponding parts in the two figures.

rlhe object of this invention is to obtain a horse-power windlass of simple construction,

which will admit of the article or machine which is operated upon by the horse-power being released from the latter at any moment at the will of the attendant.

The invention is designed to-be applied to vthe lifting of weights and the operating of l presses, such as have their followers arranged to work from the bottom of the press-box upward, whereby the weights may be lowered at any speed and the follower allowed to fall when necessary without backing the horse.

To enable those skilled in the art to fully understand and construct our invention, we will proceed to describe it.

A represents a rectangular frame, on which a horizontal wheel, B, is placed, said wheel being iitted loosely on a vertical stationary shaft, C, secured centrally in the frame A, as shown in Fig. l. The frame A has friction-rollers a attachedto it, on which the wheel B rests, the lower edge of the latter being provided with a ange, b, as shown in Fig. l. The upper edge of the wheel B is also provided with a ilange, c, which projects outward, and is provided at its under side with lugs d at suitable and equal distances apart, as indicated by the dotted lines in Fig. 2.

D is a sweep, the inner end of which is fitted loosely on the upper part of the hub e of the wheel, and secured thereon by a nut, f. This sweep has a crossbar, E, attached to it near its inner end, said bar being provided with shoes g g, one at each end, which are directly over the upper Iiange, c, of the wheel, as shown in Fig. 2.

To the under side of the sweep D there is l the wheel B by a rope or chain, and the sweep D is connected to the wheel B by shoving the slide F inward through the medium of the lever G, the slide F serving as a pawl in consequence of its inner end coming in contact with one of the lugs d. The sweep D being drawn around by the horse, the rope or chain is wound upon the wheel B, and the article thereby hoisted or elevated, and when it is to be lowered the slide F is thrown outward from the wheel B, so as to release the latter from the sweep, and the elevated article will fall by its own gravity. The speed of the falling articleis graduated by the attendant pressing down upon the outer part of the sweep,which causes the shoes g to bear upon the upper surface of the wheel B, and with greater or less friction, according to the pressure on the Sweep. In hoisting articles-such, for instance, as coal-from vessels it will be seen that the lled bucket may be lowered without backing the horse, and in operating presses which have their followers arranged to work from the bottom of the press-box upward the follower, when fully elevated, may, like the coal-bucket, be lowered without backing the horse and the speed of the descent graduated as desired.

The slide F, besides serving as a pawl to connect the sweep D with the wheel B, also serves, in consequence of its inner end being under the upper iiange, c, of said wheel, to prevent the sweep from rising or being thrown upward out of proper position--a contingency liable to occur if the horse be suddenly stopped. The invention, it will be seen, is exceedingly simple and efficient, may be constructed at a very moderate cost, and contains no parts liable to get out of repair or become deranged by use.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination of the wheel B, sweep D, and slide F, or its equivalent, arranged as shown, to admit of the connecting of the wheel to the sweep and the detaching of the former as shown, to admit of a ready connection befrom the latter, for the purposehereinset forth. tween the sweep and Wheel and to keep the 2. The cross-bar E, att-ached to the sweep D former in proper position with the latter, as and provided with shoes g g, arranged relaset forth.

tively with the wheel B, to serve, in connection L. DEDEBICK. kwith the sweep, as a brake for the latter, as P. K. DEDERICK. set forth. Witnesses:

3. The slide F, attachedY to sweep D, and the A. N. WILooX, l,

lugs d and flange c on the wheel B, arranged I A. M. DEDERICK.
